Turning on the Pixracer board LED

Here are the files to turn on the board LED that will match the Toshiba LED.
Do to the craziness of the code there are number of modifications.

In the AP_HAL_Boards.h file you need to add the following line in the subtypes:
#define HAL_BOARD_SUBTYPE_PX4_V4 2002
Replace the following lines with these lines in the HAL_BOARD_PX4 section:
#ifdef CONFIG_ARCH_BOARD_PX4FMU_V1
#define CONFIG_HAL_BOARD_SUBTYPE HAL_BOARD_SUBTYPE_PX4_V1
#define HAL_STORAGE_SIZE 8192
#endif
#ifdef CONFIG_ARCH_BOARD_PX4FMU_V2
#define CONFIG_HAL_BOARD_SUBTYPE HAL_BOARD_SUBTYPE_PX4_V2
#define HAL_STORAGE_SIZE 16384
#endif
#ifdef CONFIG_ARCH_BOARD_PX4FMU_V4
#define CONFIG_HAL_BOARD_SUBTYPE HAL_BOARD_SUBTYPE_PX4_V4
#define HAL_STORAGE_SIZE 16384
#endif

Now in the AP_HAL_PX4 folder replace the GPIO.CPP program which starts the LED driver need to make the LED work:
GPIO.CPP
Hopefully this will not break any previous version of PX4 boards.
Now in the AP_Notify folder add two new files:
PixRacerLED.h
PixRacerLED.cpp

And lastly add this new driver into the AP_Notify.cpp code:
Add this line in the include section:
#include "PixRacerLED.h"
In the HAL_BOARD_PX4 section replace AP_BoardLED boardled with:
#if CONFIG_HAL_BOARD_SUBTYPE == HAL_BOARD_SUBTYPE_PX4_V4
PixRacerLED boardled;
#else
AP_BoardLED boardled;
#endif

That's all that is needed.
